You've decided to move forward with a divorce, you've gathered your paperwork, and then it hits you — you have no idea where your marriage certificate actually is. It's a more common problem than people expect, especially years into a marriage, after a move, or when the wedding happened in another province or country. The good news: a missing original doesn't end your divorce application. It just adds a step.

Why the Court Needs Proof of the Marriage

A divorce can only be granted by ending a marriage that legally exists, so the Superior Court of Justice needs to be satisfied that a valid marriage took place before it will grant a divorce. In practice, that usually means providing the original marriage certificate or an acceptable certified copy along with the application. If you don't have it on hand, you'll generally need to obtain a replacement before — or shortly after — filing, rather than skip the requirement altogether.

How to Get a Replacement, Step by Step

1. Identify where the marriage was registered

Marriages are registered with the government of the province, territory, or country where the ceremony took place — not necessarily where you live now. If you married in Ontario, that's Ontario's vital statistics registry. If you married elsewhere in Canada, it's that province or territory's equivalent office. If you married outside Canada, it's the relevant foreign government office, sometimes accessible through that country's Canadian embassy or consulate.

2. Request a certified copy, not just any copy

Courts generally require a certified copy of the registration — not a photocopy of the original certificate, and not a religious or venue-issued keepsake certificate, which typically isn't the same as the government registration. Confirm with the issuing office exactly what document they consider the certified proof of registration.

3. Build in extra time

Requesting a replacement from a government registry — especially a foreign one — can take meaningfully longer than a routine local request, and timelines vary widely depending on the jurisdiction. If your divorce is time-sensitive, start this step as early as possible rather than waiting until the rest of your application is ready.

4. Talk to your lawyer if a replacement truly can't be obtained

In rare situations — a lost historical record, a country that no longer maintains the relevant registry, or a document destroyed in unusual circumstances — a certified copy may not be obtainable at all. Courts have some discretion to consider other evidence of a marriage in genuinely difficult cases, but this isn't something to assume applies to your situation. Get advice from a family lawyer before relying on an alternative to a certified copy.

What to Have Ready Before You Request a Copy

Frequently asked questions

Can I just use my wedding photos or officiant's letter instead of a certificate?

Generally no. Courts look for the certified government registration of the marriage, not personal or venue documentation, though your lawyer can advise if your specific situation calls for something different.

What if I was married outside Canada and that country's records are hard to access?

Start with that country's civil registry or its embassy/consulate in Canada. If access is genuinely difficult, tell your lawyer early — this is exactly the kind of situation where advance planning avoids a filing delay.

Does a missing marriage certificate mean I have to prove I'm actually married?

It means you need to obtain acceptable proof before the court will grant the divorce — it doesn't suggest the marriage itself is in doubt. Once a certified copy is obtained, this step is usually straightforward.

How long does it take to get a replacement certificate?

Timelines vary significantly by jurisdiction and aren't something we can state as a fixed number — Ontario requests, other-province requests, and foreign requests can all move at very different speeds. Request it as early as possible.
